Problem Description

I am working with a floating network license of COMSOL. How can I determine who is currently using COMSOL or a specific module?

Solution

The COMSOL installation provides FlexNet license utility programs that produce a list of current COMSOL users for all licensed products, see below for platform-dependent instructions.

For more information about the FlexNet licensing system, and more detailed options through the lmutil and lmstat tools, see the COMSOL Multiphysics Documentation page (from the GUI, navigate to Help->Documentation->FlexNet Documentation->License Administration Guide).
More advanced usage tracking is offered by third-party tools like FlexNet Manager.

Windows

Use the LMTOOLS utility:

  • Start > All Programs > COMSOL Multiphysics 5.3a > COMSOL Launchers > LMTOOLS
  • On the Service/License File tab, choose Configuration using License File.
  • Browse to the local license file C:\Program Files\COMSOL\COMSOL53a\Multiphysics\license\license.dat (NB: The Open file dialog is preset to look for .lic files. To find the license.dat file, please change the file type.)
  • Go to the Server Status page and select Perform Status Enquiry.

Linux

Open a terminal window and run these commands:

cd /usr/local/comsol53a/multiphysics/license/glnxa64
./lmstat -a -c ../license.dat

alternatively, if you know the host name of the license manager:

cd /usr/local/comsol53a/multiphysics/license/glnxa64
./lmstat -a -c 1718@licsrv

Here, 1718 is the default port, and lcsrv the host name of the license manager.

Mac OS X

Start the Terminal application and run these commands:

cd /Applications/COMSOL53a/Multiphysics/license/maci64
./lmstat -a -c ../license.dat
